` RECEPTACLE-FORMING MACHINE.

Specification of' Letters Patent.

Patented nec. 3, 1907'.

Application flied January 2.1906. serai No. 294.218.

To all whom 'it may concern:

lBe it known that I, GEORGE W. MAX- WELL, citizen of the United States,residing at San Francisco, in the'county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inReceptacle-Forming Machines, of

l preferably sheets of thick paper 4or cardI which the following is aspecification.

My invention relates to receptacle forming machines, and moreparticularly to machines for forming containing vessels from fibrousmaterial for dispensing different articles, preferably milk.

The object of the invention is to produce a machine in which blanks ofmaterial,

oard, are automatically fed in succession to gluing and bevelingmechanism, then` passed to formers and folded into hollowodies, thensecuring a bottom in each body, and finally ejecting the completedarticle.

Anvembodiment of the invention is shown in the accompanying drawings inwhich:

Figure 1 is a broken side elevation, some of the parts being omitted toavoid confusion. Fig. 2 .is a similar front elevation, Fig. 3 is asimilar plan view, Fig. 4 is a sectional view on line 4-4 of Fig. 3looking in the direction `of the arrow, Fig. 5 is an inverted plan viewof the ejector mechanism, Fig. 6 is an enlarged detail view. of thefolding mechanism, Fig. 7 is a transverse sectional view of the trimmingand gluing mechanism; Fig. 8 is a sectional view of the bottomingmechanism on the'line 8-8 of Fig. 2, Fig. 9 is.a detail view of thesame, Fig. 10 is a'detail view of the means for actuating the lowerfolder. Fig. I11 is a detail perspective of the vconnections rforoperating the bottom-seating mechanism.

Referring more particularly to the drawings, 1 indicates the frame,across the rear portion of which is mountedthe main shaft 2,. which isdriven from anysource of power, not' shown, preferably by a sprocketwheel 3 and chain 4. Located substantially in the center of the frame isthe magazine 5, in which are placed the blanks 6 from which the articlesor containers are .to be formed.

Theblanks are fed fromthe bottom of the magazine, one at a time, by areciprocatory feeder 7, which is preferably secured to or mounted on aslide 8, which is adapted to be moved back and forth on a bar 9, by alever l0 and lnk'll.

' their norma Theleveris swung on its pivot by a link 12 which isconnected with a crank or wrist pin 13 on a mutilated gear pinion 14.The pinion is adapted to be intermittently driven by a gear wheel 15 onthe main shaft 2.1 The teeth of the pinion are thrown into mesh with thegear 15 at the proper time by projections 17 on the pinion which areengaged -by pins 18 on the gear and thereby given a slight movementforward. The feeder is provided with yielding blocks or VJfingers 19,which project above the bottom pieces 20 of the magazine just thethickness of one blank, so that when it is carried forward by the abovedescribed mechanism the fingers will carry the blank forward under thelower ends of the front bars 21 of the magazine and deposit it upon acarrier 22. On the return movement of the feeder the fingers are causedto bend forward and slide under the pileof blanks Without disturbing 5Vthem and the feeder is moved far enough to the rear toy permit of thefingers assuming position before being carried forward to engage withanother blank.

' lThe carrier is mounted on the upper end of an arm 23, which is swungback and forth by a lever 24 and link25. The carrier is moved forward todeposit the blank by a pin 26 on the wheel 15 which engages with thelever 24, and it is returned for another blank by a s ring'27 which ispreferably connected with tie arm V23. The carrier is held in its normalposition by the lever 24 resting on the shaft 2.

The blank is deposited by the carrier upon a platform 28 where it isrigidly held by a clamp 29, which is reciprocated, or moved toward andfrom the platform by a stem 29 and gear segment 30 which engages with arack 30 on the stem. The rack is guided in its reciprocation by a guidepin 31 and the segment is mounted on a rock sh. ft 32, which isoscillated by a lever 33 and link 34. The lever is actuated by a crankor wrist pin 35 mounted on a pinion 36 and working in a slot 37 in thefree end of the lever. The pinion is driven by a gear wheel 38 on theshaft 2 and is mutilated so as to only move the clamp at suitableintervals to correspond with the operation of the other mechanism. Pins39 on' the wheel 38 throw the teeth of the pinion into mesh at theproper times by engaging with projections 40 on the pinion.

After the blank has been deposited upon 45 a shou der or projection v16on the lever 10 A the platform vand while it.` held by the clamp, one ofits edges is chamfered Vor`beveled 0H so that when the blank is rolledinto f smooth or even. In the drawings I have shown Aonly.one ed ebeveled lto form a 'fs'mooth interiorbut 1t is evident that both edgescould be beveled by sim ly du licatlng normally submerged in thecontentsof ably cylindrical and tapering, as vthe-frus- 'have thoughtitnot necessary to show. In

: theblank is bein beveled the other end` re- 51, as by means of a bar.52, which is pivotbeing actuated by a cam l56 on the shaft 2,

- lifts it up w en the lever' is swung backfin re theA clamp Vis movedforward the jawis per-- mitted to gradually'close so that 'by the timetubular form and its edges overlap ed, the bevel will cause the surfaceofthe tu e to be ing the beveling mechanism, ut w 'ch ,I

the form of mechanism which I have shown and prefer for beveling .theedge of the blank, a block ori slide 4I is mounted in a vguideway 42arranged-parallel with the edge `to be beveled and the block is movedback and forth belt 46 from any suitable source of power,

At the same time that one edge or'end of lceives a line of ad esivematerial from a tank .ally supported on a rock shaft 53, the bar bethetank, which is referably glue. The shaft 53 is rocked at t e proper timeto glue the blank by a lever 54 and link 55, the lever and held in'lengagement therewith by a spring'57.

After the blank has been beveled and .glued it is fed `forward onto theforming .mechanism by la reciprocatory clamp 58 which is connected withthe upper end of the lever 10. The'- up er jaw 59 of the clamp isspring* ressed an adapted to be opened by which enga es with a pinO onthe jaw and turning the feeder7 for another blank. As

the clamp has been moved forward tosecure 'a good hold uponltherear'edge of the blank the jaw is com letely closed and the blankisvcarried forwar thereby-until it lies 'directly above a 'block or former61, which is prefertum of a cone. i

When the blank isde o sitedl upon the platform 28, it is prefera ly.ositioned'by wcfprocatory lpins 62 'at the rontk and one end andinclined pins'or guides 63 at'the 'rear-and the otherl end. Before vitis moved 'forward to'thefo'rmers' the pins 62 arer de- 'pressed, aswbygearv pinions 64-'and1 racks 65,

which pinions Aare actuated by a rock shaft 66. The shaft is providedwith two arms 67 and 68, set at such an angle toeach other that themovement of one of them to rock the shaft sets the other in position tobe engaged and thereby return the shaft to its former position. Ihe arm67 for depressing the pins is located in the path of a push rod 67Whichhas one end connected with the lever 47 and its vother end with alink 68. The arm 68 for elevating the pins is in the path of aprojection 69 on the lever 10 which causes the pins to rise just in timeto receive va blank from the carrier 22.

Theformers 61 are preferably secured radially to the periphery of` awheel 70 by means of standards or vertical brackets 71.

so j

The wheel is mounted on a spindle 72 at the 'outer ends of inclined armsforming a part of the `main frame and projecting from the front thereofand is rotated, step by step, by

.a pawl 73 on a reciprocatory bar 74 so as to successively 'bring theformers under the blanks as above described. The bar 74 is drawnforwardto rotate the wheel by a rack at one end thereof and a segmental gear 75which gear is, driven'from the main shaft 2 by a shaft 76 and bevelgearing 77, and the bar is returnedby a spring 78. Thefteeth of thesegment are caused to register with those of the rack by one Iend of thesegment engaging with a projection 79 on the rack and giving-the rack vaslight movement before the' teeth are thrown into engagement. thesegment passes out ofengagement with the rackva pin at the rear end ofthe segment After engages with an inclined projection on the rack andacts as a brake T,to prevent ythe sgring i78 from drawing back 'the bartoo rap- 1 The wheel 70 is locked with a former inposition to receive ablank by a shoulder 80,l

against which a projection 81 at thenpper end of each bracket71 isadapted to engage as the wheel is moved forwardI by the pawl 73. Thepawlis pivotally secured so as to pass under thelower end of the bracket 71on the return movement of the bar 74, and it is preferably yielding, asby mountin it at the ulpper end of a pivoted arm 82,`the ower end o thearm being connected to a spring 83.

The' stop or/shoulder 80`is also preferably yieldlng, as by 'utilizingor forming it at the lower end of a pivoted arm 84, theupper end of thearm being connectedwith a spring 85. The shoulder isformed on orconnected with a laterally movable bar 86,-which is"pivot ally securedat one side of the machine and supportedii a'stirrup 87 at theotherside, and provided iwith a\deflector 88 at a distance from-theshoulder 80 equal. to the width of theprojection 81. ,One side or faceof the deflector is -slightlyinclined so that whenit is engaged by thero'ection 81, the bar 86, which'is normally field in its locking s'asstposition by a spring 89, will be drawn over until the projection hascleared the deflector, when the spring will immediately draw the barback and cause the projection to stand between the dei'lector and theshoulder 80.

Before moving the wheel forward after a blank has been deposited on theformer, the free end of the bar 86 is moved laterally in the stirrup bya lever 90, which moves the shoulder 80 from in front of the projection81 and permits the pawl 73 to move the wheel forward another step. Thelever 90 is actuated by a cam 91 on the shaft 76 which engages with aninclined surface 92 on the lever and throws the bar over after which thespring 89 will return the bar to its normal position as soon as the campasses out of engagement with the incline 92.

When the wheel is standing in its locked position the forward end of oneof the formers 61 is held adjacent to the end of bar 9, with a pin 93 inits end resting on support 94 on the frame 1, so that as the clamp58.moves forward the blankslides upon the former until its forward edgeengages a stop 95 on the former and the clamp enters a -slot 96 formedlongitudinally in the end of the former. The stop 95 is preferably madeadjustable, as by slotting it and fastening it in particularly adapted.

position, as with an .ordinary screw. This ,secures accuracy in formingthe receptacle when it is intended to hold a predetermined quantity, asmilk, for which the receptacle is In case the edge of the blank shouldengage with the stop before the clamp 58 reaches the forward limit ofits movement the spring pressure upon the jaw 59 will permit of theclamp moving forward a short distance without moving or damaging theblank.

After the blank has been deposited on ,the former in this manner, a pairof reciprocatory press-like clamps or folders 9,7 'descend and, owing totheir being substantially inverted U-shape, they press the blank downupon the upper portion of the formers with the ends of the blankprojecting below it substantially parallel.. After that the ends arefolded in upon the under side of the former with their edgesoverlapping, by twoside folders '98 and .99 anda bottom folder 100. Thetop and side folders are operated by a train of gear wheels 101, .102and 103, of sub- `stantially the same size, and threemutilated pinions,104, and 106, which mesh relspor-tively therewith. The wheels aredriven` stem 113 rojecting upward from the head 114, and t ereby causesthe head to be reciproeated on downwardly extending pins 115. carry theside clamps, respectively, 'are pivotally mounted on the stem 113, andthe clamps, which are curved and rigidly secured to the free ends of thelevers, are carried respectively above and below the plane of the blankby the reciprocation of the'head 1 14. After the presses97 have beenlowered to seat the blank on the former, the pinion 105 stops rotatingand the side clamps are moved toward the former, one in advance of theother, the folder 98, which folds the beveled edges, moving slightlyahead of the folder 99, and after reaching the limit of its movement thepinion 106, which controls it, is disengaged from its gear wheel 103,and like the pinion 105, remains stationary until the folding process iscompleted. When the The arms or levers 116ar'1d 11.7 which i parts standin this position the beveled edge y abuts or rests, against the oppositeor glued end of the blank at, substantially a right angle and thefurther inward movement of the folder 99 would have a tendency to bendoricrumple the thin beveled edge in trying to force it in against vtheformer. To revent this ,the pinion 104 is stopped and the ottom folder100 is moved up into engagement with `'the rojectin vor glued end of theblank whi causes it to bend and present an inclined surface upon whichthe beveled edge will slide. The pinion 104 is then again thrown intoengagement which will cause the folder 99'to foreethe glued oroverlapping end inward simultaneously with the continued upward-movement of the bottom folder 100 until the lap is completed when thepinion 104-again stops and the bottom folder completes its movement andholds the overlapping ends 'of the blank together.v

After the blank is thus secured all ofthe inions are .thrown intoengagement with t eir respective gear wheels and the top and sidefolders are returned to their normal position, when they again stop. andremain lstationary until another blank'has been deposited and -thefolders are again operated as above described.

The bottom folder 100 is pivotally mounted inits support and providedwith a tail piece or projection 118, which is adapted to h e engaged bythe free end of a push bar 119 that is mounted on two legs or supports120 and 121.

its normal position, its free end will engage with the projection 118and follow it up as the folder is swung upon its pivot until a pin 122on the rejection engages with a latch 123and loc s' the folderinengagement with the lap of the blank on the former as above described.The free end of the other leg 121 The leg\-120 is pivoted at such a l..distance i .advance of its connection with `the bar tha ,asthe barmoves forward from extends above its connection with the bar and isadapted to be engaged by a pin 124 on -the former and clamped by theheated folder 100, the wheel 70 is unlocked and fed forjward, step bystep, as hereinbefore dewhich the'latch 123 is moved into engage-4 i Ithe main shaft 2 and a lever 139, the wheelbeing wide enou h tohave thebar and rack scribed, until the former vcarrying .a blank has almostmade a complete cycle and reaches the ejector mechanism, just beforement with a stop 128, which causes it to release the bottom folder andpermitthe folder `to fall away from the former. By this time the lue hasbecome. thoroughly driedfand the' lank has been formed into an openended tapering conical tube ready to have a bottom inserted therein.

Mounted radially of the Wheel and directly above the former from whichthe bottom folder hasl just been released, is a reciprocatoryzpl-unger129 to which are secured two depending brackets 130. The plunger ismoved forward and back by a gear wheel 131 and rack 132,- and to thelower end of each of the brackets is pivotally secured a forwardlyextending, springpressed arm 133.` A curved head or ejector 134 isysecured to the free end of each arm which is adapted to be forced into'engagement with the former by a pin 135 which is adapted to engage witha guidev 136. There are two guides which have their forward ends freeand inclined toward each other, whereby, When the lunger is movedforward .the heads will be orced in against o posite sides of the formerto the rearof the arger -end of the tube and' held in yieldingengagement therewith until they have forced the tube off the tip orsmaller end of the former. By the time this has been done, another blankhas .beende-4 posited upon the former which has been locked below thefolding mechanism, and the wheel is then again unlocked and fed forwardanother step which l-places -another former in position to receive ablank andanother former inposition to have a tube -re-l moved`therefrom. The wheel 131 is oscillated to reciprocate the plunger by atoothed bar 137 which lis actuated by a cam 138 on both engaging terewithat the same time, one above the other.

When the tube passes off the -end of the former it drops into a basketor .cage v140 depending from one end of the plunger support 141, whichoverhangs a hor1zontally-4 arranged rod or carrier 142', in.which are"formed openings or pocketsl 143. The rear end of the 'cage 140 1sl intheform Lof a loop which engages with the larger endof tube as it fallsfrom thev former, while the forward end is formed from slender arms, twoof which'are at the .sides and the other one at f of the tube, whichwill cause the theend smaller end of the tube to fall down into one ofthepockets 143, while the loop at the rear, by arresting the` downwardmovement of the larger end of the tube,`will cause the tube to assume asubstantially vertical position in the pocket, something like a hopper.n

The reel is caused to revolve, ste by a spring pressed pawl 144, whic ispivotallyl mounted on the end of the reci rocatory bar 74 which isextended under the reel in by step, l

position tolet the pawlv enga e with shoul'- ders thereon; as the spokeslo the reel. its revolution, the reel carries the tube under aredischarged, one at a time, into theotubes cated by two levers 147 and'.148 which are amagazine 145'in whichI are stored the bot;- tomstherefor and from which the bottoms by an ejector 146. lTheejector isreeipro connected by a-link 149, and actuated by'a cam 150 on a shaft151, which inturn is driven from the -shaft 2 by gear wheels 152.

' The ejector is yieldinglyl forced forward by a Spring 153 which en geswith the lever 148',

while it is drawn bac positively for engaging with another bottom bytheengagement of'4 thevcam7 150 with saidlever 148. In `this Y.

manner the liability of damage to the machinery bythe failure oftheejector lto discharge a bottom isavoided. l

Just beforezthe bottom is deposited inthe I tube,x a temporary support,as a circular platform ,154, is permitted to rise in the' lolwer end ofthe 'tube and causel the bottom to restI at right angles to the axis'ofthe tube-and thereby prevent its being caught or held inthe wrongposition. After the bottom has been.-

deposited in this manner, a plunger 155 descends and forces it down intothe tapering end of the tube until itsl edges engage sofirmly therewiththat a water tight jolnt is formed and the'bottom will be heldagainstaccidental displacement'. The plunger is reciprocated, by a lever 156,whichis connected .by a link 157 with the plunger rod below ,a

head 158 and `thelever is depressed by a cam mal position'by a spring160.

As it is desirable for :the finally seated `with a. slow movement, andowingto the speedwith which thel plunger must travel to Venter-thelo'ng`tube and be withdrawn in time to permit ofthe rotationof the reel, asupplemental lever 162 is arranged to en age with -the-head y158 withits short end 'w er1-the' plungeris depressed,

bottom to be A 159 on the shaft`151, and returned to its nor- .while itslong end isactuated by a cam arm .l

163 nthe shaft 151.1 Asthe lever 162l nor- ,mally stands with its shortend retracted or Withdrawn, it is necessary to throw the head under saidend after it descends far enough to be engaged thereby, which is done by'1n-v clining one edge as at 164 which, engages with a pin or upright165, and causes the head to be swung in under said end of the lever andbe engaged thereby when the free v end of the lever -is engaged by thecam arm During the final pressure upon the bottom the tube is supportedby its lower edge resting upon a movable platform 166, which is swung upinto position by a'lever 167 that engages at one end with the platformand has its vopposite end in position to be depressed by a pin 168 onthe link 157, which causes the platform -to rise simultaneously with thedepression of the plunger. The

4platform is slotted for the passage of the stem of the circularplatform 154 and the circular platform is reciprocated or withdrawn fromthe bottom of the tube by a push rod- 169, to permit the reel to rotateand the rod is connected with the stem of the platforin its retractedposition by a spring 171 and is moved forward to depress the platformbya 1 cam 172 on the shaft 157.

After the bottom has been placed in posif tion as above described thereceptacle is carf ried forward by the reel untilit is engaged by1 anupward extension or lfinger 17 3 on the forward end of a lever 174,which engages the bottom and lifts the receptacle up out ofiA itspocket, whence it may be moved in Iany'V desired manner but preferablycarried by i suitable mechanism, not shown, through a parafiining bath,as shown in dotted lines at 175. The lever 174 is actuated by a'cam arm176 on the shaft 151, and the arm also actuates a lever 177 whichisshouldered at its forward end so as to engage with a shoulder'on thereel, as one of its spokes, and stop ceiving it, after which it isfolded around the former and held thereon until the'glue has becomedried and it is carried around to the ejector mechanism. From there itis discharged into the bottoming mechanism where'the bottom is put inand the receptacle is discharged, complete and ready for use for manypurposes, or for further treatment toprepare it for use for otherpurposes, as` de- ;instead of gas. by a bell crank lever 170. The rod isheld in sired. As the machine is adapted to be operated step. by stepand can be provided with a large number of formers, the different stepsin the process of manufacture can be carried on simultaneously upondifferent receptacles, where the capacity of the machine will be verylarge.

Although I have shown a form 'of mechanism which I have found veryefficient for practicing my invention, it is evident that modificationscan be made therein, and I reserve the -right to make all such changesand alterations therein as will come within the scope of my invention.For instance, the edge- 'of both ends of the blank may be beveled ashereinbefore mentioned, which adapts the receptacle for receiving acap-like bottom upon its exterior, and angular receptaclesl can beformed instead of cylindrical by constructing the former with thedesired outline or cross section and making the folders of the propershape to conform thereto. Or electricity can be used for drying the glueHaving described my invention, what I .claim as new and desire to secureby Letters Patent, is-
